7.5 ns propagation delay — timing budget anchor
The ATF16V8C-7JU is a high-performance electrically erasable programmable logic device (EE PLD) from Microchip, part of the 16V8 family. Its 7.5 ns propagation delay sets the maximum combinatorial path the logic can close without pipeline registers — at 5V supply, this translates to a typical operating frequency around 100 MHz for registered paths, though the actual Fmax depends on the macrocell configuration and routing. The 8 macrocells provide the logic capacity for address decoding, bus arbitration, state machines, or simple glue logic consolidation.
20-PLCC J-lead — footprint and reflow
Housed in a 20-lead PLCC (J-Lead) package, the ATF16V8C-7JU occupies a 9x9 mm body footprint. The J-lead form factor requires a PLCC-specific land pattern — the solder joint is under the package body, so visual inspection of the heel fillet is limited. Reflow profile should follow JEDEC J-STD-020 for the PLCC package; the J-lead has a lower coplanarity tolerance than gull-wing, so the stencil aperture and paste volume must be controlled to avoid opens. The 5V supply rail is the only power input — no core or I/O split.
Microchip lists the ATF16V8C-7JU as Active. For a BOM line using this PLD, the supply risk is low — it remains a current catalog item, not a legacy part being phased out.
